Sorry, I misunderstood. I know about all that, I just thought it meant active infrared lighted cameras. So basically, an IR light on the car, illuminating the road ahead, and then just using a near-IR camera like a regular optical camera.

I didn't think it meant a far-IR camera passively filming black body radiation, because I thought the resolution (both spacially and temporally) of these cameras is usually really low. Didn't think they were fast and high-res enough to be used on cars.
